Abstract
Background & objectives: The aim of the present study was to evaluate 8 weeks individualized balanced low calorie diet on anthropometric measurements in apparently healthy obese women.
Methods: Forty apparently healthy obese women (age: 18-40 years and 27.5≤BMI≤40 kg/m2) were recruited from the nutrition clinic in Ardabil city. The participants received a balanced low calorie diet after anthropometric measurements. Paired T-test was used to compare the changes during 8 - week intervention.
Results: Individualized balanced low calorie diet resulted in a significant decrease in body weight (-3.99±0.34 kg, p<0.001), body mass index (-1.61±0.14 kg/m2, p<0.001), waist circumference (-2.91±0.32 cm, p<0.001), hip circumference (-1.89±0.37 cm, p<0.001), waist to hip ratio (-0.01±0.004, p=0.001), waist to stature ratio (-0.02±0.002, p<0.001), body adiposity index (-0.97±0.15%, p<0.001), abdominal volume index (-1.07±0.11, p<0.001) and conicity index (-0.007±0.002, p=0.001) during 8 weeks.
Conclusion: Based on the results, an individualized balanced low calorie diet induced weight loss and decreased other anthropometric measurements during 8 weeks. Balanced low calorie diet-induced moderate weight loss alone can be a good way to reduce metabolic risk factors in obese women. .

Abstract
Background & objectives: There is a direct relationship between the presence of beneficial microbiota in the gut, development immune system functions and maintenance homeostasis. Hence, the consumption of foods or supplements with postbiotic components has been characterized as one of the most important strategies to modify the microbiome balance and improve the health status of the host. In this study, the concept of postbiotics and their clinical role in host health has been reviewed.
Methods: All articles related to the study subject were searched in the Scopus, PubMed/Medline, ISI Web of Knowledge, and Google Scholar database and studies that examined the effects of postbiotics on diseases were included.
Results: According to available evidences, postbiotics do not need the viability in comparison with their parent cells and they exert health effects like live probiotic cells. Also, their preparation and application in various delivery system is affordable, which this highlights the importance of postbiotics from technological, clinical and economic aspects. These compounds have biological activities including immunomodulation, antimicrobial, anti-inflammatory, anti-oxidant and anti-proliferation, and they can play an important role in modulating the immune system's performance, improving therapies and reducing their possible side-effects in some cases of gastrointestinal disorders and chronic diseases.
Conclusion: The postbiotics as a novel strategy can be used in a wide range of pharmaceutical products for the preventive therapy and improvement of the current therapeutic methods, as well as in food products to delay corruption, increase shelf life, and promote functional foods.

Abstract
Background & objectives: Probiotic dairy products as a functional food have a positive effect on the health of consumers that have been confirmed by scientific evidence. Yoghurt is considered as one of the most popular dairy foods in Iran, which the incorporation of the probiotics into the yoghurt matrix can improve their microbiological and sensory properties and subsequently will play a vital role in promoting the health of the community. The aim of this study was to investigate the effect of yeast Kluyveromyces marxianus on the microbial and sensorial properties of probiotic yoghurt during refrigerated storage.
Methods: In this in vitro study, the yeast Kluyveromyces marxianus PTCC=5189 was used to produce probiotic yoghurt and Aspergillus parasiticus PTCC=5018 (IR 63) and Penicillium chrysogenum PTCC=5074 were used as known pathogens and the main spoilage agents in yoghurt. Changes in the number of probiotic yeasts and spoilage species as well as the sensory acceptability of the samples during 28 days of storage at 4°C were evaluated and compared with the control samples.
Results: The population of both species, involved in yoghurt spoilage, during refrigeration were significantly reduced by the presence of Kluyveromyces marxianus (p<0.01). After 28 days of storage, the number of Kluyveromyces marxianus was at the recommended level of the International Dairy Federation with a 7.35 log CFU/g. The sensory evaluation results demonstrated that the control yoghurt samples were more acceptable.
Conclusion: Kluyveromyces marxianus has a significant effect on improving microbiological properties and can be used in the formulation and production of probiotic yoghurt with high storage capability and optimal sensory acceptability.

Abstract
Background & objectives: Considering the high prevalence of body image dissatisfaction and its consequences, it is necessary to consider effective interventions to reduce it. The aim of this study was to investigate the effect of a balanced low calorie diet (BLCD) and slight weight loss on the body image score and its subscales.
Methods: In this clinical trial, 74 apparently healthy, non-pregnant, non-lactating and non-menopausal women (age range: 18-49 years with body mass index range: 27.5-40 kg/m 2) were selected using random sampling method from a nutrition clinic in their first visit in Ardabil city between November 2019 and February 2020. Data collection was done by Anthropometric measurements and multidimensional body self-relations questionnaire. The paired T-test was used to compare the changes during 4 - week balanced low calorie diet intervention. BLCD was an individualized diet with an energy deficit of 500 calories of daily energy intake that was calculated from 3-day food records for every person.
Results: After 4 weeks, BLCD resulted in a significant decrease in body weight ( p=0.001), body mass index ( p=0.001), waist circumference ( p=0.002), waist to height ratio ( p=0.012), abdominal volume index ( p=0.009) and conicity index ( p=0.045) and a significant increase in the subscale scores of fitness evaluation ( p=0.01), health orientation ( p=0.03), body area satisfaction ( p=0.01) and overweight preoccupation ( p=0.001).
Conclusion: According to the results, it seems that even slight weight loss with a balanced low-calorie diet can be effective in improving anthropometric indices and some subscales of body image in 4 weeks. These results support the effectiveness of short-term interventions.
